Abstract
After the disastrous Gorkha earthquake struck Nepal, on April 25, 2015, a large amount of building waste was generated by collapsed residential buildings and dilapidated buildings. This paper outlines the on-site damage investigation of the area affected by the earthquake with different types of waste produced from each building were estimated and evaluated based on the type of building. An estimation procedure was established in order to assess the amount of debris resulting from the earthquake. In Kathmandu Valley, different types of buildings generate different quantities of building debris per unit area and the values for these building types ranged from 1.89 to 3.08 tons/m2 of debris. The results of this study will allow estimation of the amount of building debris and thus aid for emergency response teams after disasters such as earthquakes and also with pre-disaster planning, allowing for proper management and efficient operations.
